هوای تهران در هفتمین روز سال مطلوب است

بر اساس اعلام شرکت کنترل کیفیت هوای تهران، کیفیت هوای پایتخت امروز (۷ فروردین ماه) در شرایط قابل قبول (سالم) است.

به گزارش ایسنا، براساس اعلام شرکت کنترل کیفیت هوای تهران میانگین کیفیت هوای پایتخت طی ۲۴ ساعت گذشته ۷۹ و هوا در شرایط قابل قبول (سالم) بود. این شاخص هم‌اکنون ۵۳ و هوا در شرایط قابل قبول است.

بر اساس این گزارش شاخص کیفیت هوا (AQI) به پنج دسته اصلی تقسیم‌بندی می‌شود. بر اساس این تقسیم‌بندی از عدد صفر تا ۵۰ هوا پاک، از ۵۱ تا ۱۰۰ هوا قابل قبول(سالم) یا متوسط، از ۱۰۱ تا ۱۵۰ هوا ناسالم برای گروه‌های حساس، از ۱۵۱ تا ۲۰۰ هوا ناسالم برای همه گروه‌ها، از ۲۰۱ تا ۳۰۰ هوا بسیار ناسالم و از ۳۰۱ تا ۵۰۰ شرایط کیفی هوا خطرناک است.

گفتنی است در هوای پاک که با رنگ سبز نشان داده می‌شود، شرایط کیفیت هوا مناسب است و خطری برای سلامت انسان ندارد. در هوای سالم که به رنگ زرد شناخته می‌شود، کیفیت هوا قابل قبول و غلظت آلاینده‌ها کمتر از حدی است که بر سلامت انسان تاثیر منفی داشته باشد، اما در هوای ناسالم برای گروه‌های حساس که به رنگ نارنجی نشانه‌گذاری می‌شود، مقدار AQI بین ۱۰۱ تا ۱۵۰ قرار می‌گیرد که در نتیجه آن گروه‌های حساس اثرپذیری بیشتری از آلودگی هوا خواهند داشت.

در هوای ناسالم که به رنگ قرمز است، کلیه افراد جامعه در معرض مخاطرات ناشی از آلودگی هوا قرار می‌گیرند و حتی ممکن است گروه‌های حساس دچار عوارض شدیدتری شوند. افزون بر این در هوای بسیار ناسالم که به رنگ بنفش نشان داده می‌شود و عدد AQI بین ۲۰۱ تا ۳۰۰ قرار می‌گیرد، احتمال بروز عوارض جدی برای سلامت افراد جامعه افزایش می‌یابد.
